Electroacupuncture for post-stroke depression: a systematic review and meta-analysis of randomized controlled trials.

After a stroke, many survivors experience depression — a condition known as post-stroke depression (PSD) — that can slow recovery and reduce quality of life. Researchers wanted to know whether electroacupuncture (EA), a form of acupuncture that uses gentle electrical stimulation through needles, could help treat this condition without relying solely on medication.

A team of researchers analyzed 11 carefully selected clinical trials involving 853 stroke survivors who had developed depression. They compared patients who received electroacupuncture — either alone or alongside standard treatment — against those who did not.

The results were encouraging. Patients who received electroacupuncture showed meaningful reductions in depression scores on two widely used scales: the Hamilton Depression Rating Scale (HAMD) and the Self-Rating Depression Scale (SDS). But the benefits didn't stop at mood. Participants also showed improved stroke recovery scores, better ability to perform everyday activities, and a higher quality of life. Researchers even found measurable physical changes: increased blood flow to the brain and higher levels of serotonin (a brain chemical closely linked to mood) in the bloodstream.

Electroacupuncture also outperformed traditional needling acupuncture alone, with significantly higher rates of overall clinical effectiveness.

What does this mean for you? If you or a loved one is recovering from a stroke and struggling with depression, electroacupuncture may offer a meaningful, drug-free complement to standard care. It appears to support both emotional wellbeing and physical rehabilitation at the same time — a combination that could make a real difference in recovery.

The researchers did note that more high-quality studies are needed to strengthen confidence in these findings.

This systematic review and meta-analysis evaluated the efficacy of electroacupuncture (EA) for post-stroke depression (PSD), analyzing 11 RCTs (n = 853) identified through seven electronic databases up to May 2025. Meta-analysis using RevMan 5.4 and Stata/MP 17.0 demonstrated that EA significantly reduced HAMD scores (MD = -3.68, 95% CI: -5.78 to -1.59, p = 0.0006) and SDS scores (MD = -3.08, 95% CI: -5.94 to -0.21, p < 0.0001), alongside significant improvements in NIHSS scores (MD = -1.85, p = 0.0008), ADL scores (MD = 23.45, p < 0.0001), and WHOQOL-BREF scores (MD = 1.85, p < 0.0001). Subgroup analysis showed EA outperformed simple acupuncture in effective rate (RR = 1.38, p < 0.0001). Notably, EA significantly increased regional cerebral blood flow and plasma 5-HT levels, suggesting neurobiological mechanisms of action. Clinical takeaway: EA demonstrates multimodal benefit in PSD — addressing mood, neurological recovery, and functional independence — though findings should be interpreted cautiously given the low methodological quality of included primary studies.
